Not exactly. The 'reptilian brain' is an outdated conceptual model that includes the brainstem and basal ganglia. The subcortex is a modern anatomical term encompassing structures beneath the cortex, including but not limited to parts of that old model.
Yes, 'subcortical strokes' are common and affect the small, deep blood vessels supplying structures like the basal ganglia and internal capsule, often leading to motor deficits.
Parts of it, yes. Structures like the amygdala (part of the limbic system within the subcortex) are central to emotional processing, especially fear and reward.
In strict anatomical definitions, it is often excluded. The subcortex typically refers to structures deep to the cerebral cortex, while the cerebellum is a separate hindbrain structure with its own cortex. In broad, non-technical usage, it might be included.
